Definitions

  • the first category involves traditional methods including manually applied liners and cover shotcrete, grouting and placed thermoplastic liners.
  • the second category includes placed thermoplastic liners installed automatically, using materials such as uPVC and HDPE and cover mechanically or thermally expanding the thermoplastic liner against the conduit wall.
  • the third category involves the placement of generally thermoset or catalysed or UV radiation energy cured liners which are typically placed through the eversion of an already resin-impregnated "sock" generally of fibreglass materials.
  • a newer system employs a resin coating on the surface of a flexible tube of aligned polypropylene fibres.
  • Such substrates may include repair and/or sealing compounds (eg cementitious or polymer grout) or a layer of material for enhancing the engagement of the tube structure with the conduit or the filling of the surface of the inside of the conduit.
  • repair and/or sealing compounds eg cementitious or polymer grout
  • a layer of material for enhancing the engagement of the tube structure with the conduit or the filling of the surface of the inside of the conduit.
  • the substrate substance can be applied in the same pass as the placement of the everting tube structure.
  • the process may involve placement of the substrate substance first with a removable or sacrificial liner that inflates to hold the substrate substance into position whilst it hardens. Then during a second pass the everting tube structure can be added once the substrate substance has hardened enough to absorb the water and provide a dry surface to allow the resin to cure to it.
  • a differential pressure gradient may exist between the chambers such that a pressure flow is generated from rearmost chamber to frontmost chamber.
  • the preparatory work may also involve the application of a preparatory material to the interior surface of the conduit.
  • the preparatory material may comprise a low viscosity adhesive which can be sprayed or otherwise applied.
  • the forward portion of the apparatus in the preferred embodiment may also incorporate a collection means for collecting debris within the conduit prior to installation of the tube structure to provide the liner.
  • the collection means may comprise a suction system for collecting the debris.
  • the free end of the lance structure may be configured to spread the collapsed wall of the tube structure to create a cavity to receive the resin.
  • Such means may be part as a quality control system upon which the body may react, or communicate to a remote operator who may provide remote control or through a remote feed back loop to the pressure control to the pumps and the liner pull to vary the speed of advance.
  • This can also control the feed pressure for the resin injection into the everting tube structure and the inflation pressure of the pressure chamber and the tube structure as well as the vacuum on the tube structure. In this way, the apparatus can be self controlling to ensure the optimum rate of progress is maintained. This can then be plotted and the plot provided to the customer.
  • Figure 9 is a schematic cross sectional view of a tube structure which provides the liner, the tube being shown in a collapsed condition
  • Figure 23 is a schematic end view of a brake slide structure forming part of the apparatus shown in Figure 20;
  • Figure 42 is a view illustrating the former being used to assemble the outer layer of the tube structure about the inner layer
  • Figure 45 is a schematic end view of the inner former
  • Figure 46 is a schematic plan view illustrating the folding mechanism in operation to subject the tube structure to a folding operation
  • the design of the lance structure 73 is such as to provide a base attached to the pressure plate 65 of small circumference and the protrusion 74 of a larger circumference.
  • the lance structure 73 follows the general shape formed by the tube structure as it is everting, with the everting face itself being the point of highest pressure and the area just before the everting face being a point of low pressure. Therefore, it is easier to form a cavity just behind the everting face.
  • the cavity 76 into which the resin is delivered creates a "wet-out chamber" within the collapsed tube structure 17 for the purposes of initially presenting resin to the tube structure.
  • the objective is the creation of a long "wet-out" chamber by the hydraulic force of the resin bulging the everting tube structure 17.
  • the installation head 21 further includes a guide structure 81 about which the tube structure 17 passes as it everts.
  • the guide structure 81 comprises a guide ring 82 having a ring body 83 with a central opening 84 therein.
  • the ring body 83 presents a guide surface 85 about which the tube structure 17 turns, with the inner tube portion 31 entering the ring body 83 through the central opening 84 and the everting portion 33 passing around the guide surface 85 such that the outer tube portion 32 leaves from the outer periphery of the ring body.
  • the air flow will dislodge debris such as sand and gravel particles and displace water resting in any cavities of the pipeline 15 by either blowing it out in front of the installation head 21 for collection or, if there is a hole in the pipeline 15, by displacing the water and debris through the hole to the outside of the pipeline.
  • the apparatus 10 can also operate in a pipe that is under the water table by displacing the water by air pressure.
  • This embodiment also incorporates the feature of a clamping seal mechanism 191 for clampingly retaining the outer tube portion 32 in sealing engagement with the interior surface of the pipeline 15. This is for the purpose of blocking rearward flow of resin to ensure that there is an ample coating of resin between the interior surface 13 of the pipeline 15 and the outer tube portion 32 in the section 193 thereof immediately rearward of the everting portion 33 of the tube structure 17.
  • the resin is contained at one end by the clamping seal mechanism 191 and at the other end by the pressure plate 65 and the annular seal 104 therearound. This ensures that there is ample resin between the interior surface of the pipeline 15 and the section 193 of the liner rearward of the everting portion 33 for bonding purposes.
  • the collapsed tube structure 17 is delivered from a reel 251 about which it is wound.
  • the reel 251 has provision 253 for coupling the end of the air path 247 to the suction source.
  • Various embodiments described previously utilise a tube structure 17 having an inner layer 17a and an outer layer 17b.
  • Figures 37 to 48 of the drawings illustrate an arrangement for conveniently constructing such a tube structure 17.
  • the construction path has various operational stages, comprising a first forming stage 261 , a second forming stage 262, a third bonding stage 263 and a fourth folding and pressing stage 264.
  • the second and third stages 262, 263 are integrated in a single unit 267.
  • the bonding action is performed at the third bonding stage 263.
  • the bonding process typically involves adhesive bonding. This completes construction of the inner portion in its tubular form, and it is then wound onto a storage reel 293 at the second end 252.
  • the outer former 303 is positioned around the inner former 302, with the press wheels 309 received within the channels 306 and portions of the tubular structure 17 interposed therebetween. Relative movement of the inner and outer formers 302, 303 with respect to the tube structure 17 causes the press wheels 309 to press portions of the tube structure 17 into the recesses 306 and thereby progressively create the re-entrant folds.
  • the service lines 310 extend to the installation head 21 from a station 311 located exteriorly of the pipeline at the end thereof which the installation head 21 approaches during the lining operation.
  • the station 311 accesses the underground pipeline 15 by way of access hole 313 in the ground 315.
  • the necessary length of each service line progressively reduces and so surplus service line is wound onto reels.
  • a patch as a strip extending along the longitudinal extent of the pipeline, or at least along part of the length thereof, without needing to line the entire pipeline.
  • This can be achieved in a similar fashion to the patching operation described above, the only difference being that a strip of resin absorbent material constituting the first layer is positioned at an appropriate location on the membrane constituting the second layer of the tube structure. The strip is then applied to the pipeline in a similar fashion to the discrete patches as described above.
